The 1933 Patek Philippe Henry Graves Supercomplication, in the history of watchmaking, occupies a truly prominent position, being both known as the most complicated model ever produced, and as the watch sold at auction at the highest price ever.

This model came about as a result of a competition, in which the car manufacturer James Ward Packard and the banker (and owner at the time of the Patek Philippe company) Henry Graves, among others, competed for the world's most complicated watch.

In order to boast the elitist title Henry Graves went so far as to spend 60000 Swiss Francs, more than 5 times the amount invested by his rival: the result of his project was a pocket watch with 24 functions (super-complicated, in fact) including moon phases and a daily star map of the night sky over New York.

Made using the most advanced techniques of the time, the 1933 Henry Graves Supercomplication cost Patek Philippe three years of work, from design to assembly, but its uniqueness and perfection still make it one of the most sought-after pieces by museums and private collectors, sold at auction for the first time in 1989 by the heirs of Henry Graves at the Time Museum in Rockford, it was then resold following the closure of the museum a first time in 1999 and finally in 2014, when it was listed at a Sotneby auction for $24 million, setting an all-time record for a watch sale.
